Abstract
The optical-limiting performances for four pentaazadentate metal complexes in tetrahydrofuran have been measured at 532 nm for 35-ps pulses, in which reverse saturable absorption from the singlet–singlet excited states should be responsible for the limiting mechanism. The excited-state parameters are calculated according to a six-level model. The limiting threshold at T/ T 0 = 0.5 is 44 mJ/cm2, and the throughput is limited to 27 mJ/cm2 as incident fluence reaches 0.35 J/cm2 for carboxyl pentaazadentate cadmium. The limiting thresholds and the throughput values are strongly influenced by peripheral substituents and central metal ions of the complexes.
